Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
UCLA and Northeast Valley Health Center (NEVHC), a large, multi-site Federally Qualified Health Center (FQHC), are partnering to address underutilization of the prophylactic HPV vaccine among underserved, ethnic minority adolescents receiving care through FQHCs. We will use a cluster randomized 2x2 stepped-wedge factorial study design, implemented in seven NEVHC clinics, to compare the effectiveness of parent reminders (mailed and text), multi-component clinic system strategies, a combined intervention (parent reminders + clinic system strategies) and usual care on HPV vaccine series completion among NEVHC adolescent patients. FQHCs provide essential health care to underserved groups and have the infrastructure to sustain effective strategies to improve preventive care delivery. Therefore, study findings will be invaluable for informing future efforts to improve HPV vaccination at the population-level.
